JetKVM is an open-source KVM-over-IP device firmware that enables remote keyboard, video, and mouse control over a network. The system is built as a full-stack embedded application: a Go backend orchestrates hardware interfaces (USB gadget emulation for HID, mass storage, audio, serial console), video capture and encoding (H.264/H.265 via Rockchip MPP), WebRTC streaming, OTA updates, MQTT integration, and network management. A React/TypeScript single-page application provides the web-based KVM console with real-time video, keyboard/mouse input, virtual media mounting, serial terminal, and device settings. The architecture separates a native C/C++ layer (LVGL UI, video pipeline) from the Go application via gRPC and a Unix socket, enabling failsafe mode and modularity. The codebase demonstrates strong engineering practices: extensive E2E tests against real hardware, a comprehensive OTA update system with GPG signature verification, a custom HID RPC protocol over WebRTC data channels, and a transactional USB gadget configuration system. While tightly coupled to Linux and Rockchip hardware, many internal packages (sync wrappers, confparser, changeset, playout delay interceptor) are well-isolated and could be reused in other Go projects.
